FLEXIBLE METAL BAND FOR TRACTION-WHEELS- SPECIFICATION forming part ofLetters Patent No. 766,330, dated August 2, 1904.

Application filed May 6,1904. Serial No. 206,770.

To all whom, it puny concern:

Be it known that I, EGBERT O. DoAx, a citizen of the United States,residing at Sac City, in the county of Sac and State of Iowa, haveinvented a New and Useful Flexible Metal Band for Traction-*heels ofManure-Spreaders, of which the following is a specification.

My object is to provide a band adapted to be detachably placed on thecarriage-wheel of a manure-sprezuler, traction-engine, or anytractionwheel in any form of vehicle for the purpose of increasingfriction on the ground or road whereon the vehicle is advanced, fortransmitting power from the wheel to machinery combined with thevehicle, or for preventing a traction-wheel from slipping on its track.

My invention consists in the construction, arrangement, and combinationof parts, as hereinafter set forth, pointed out in my claims, andillustrated in the accompanying drawings, in which- Figure 1 is aperspective view of a flanged metal plate adapted to be fixed on thefixed tire of a wagon or carriage wheel and also adapted to be fixed ona band adapted to be detachably placed on the lixed tire of a wheel.Fig. 2 is a transverse section of the plate that shows how steel calksare fixed to the plate by means of screw-threads. Fig. 3 is amodification of Fig. 2 and shows a calk provided with a head forfastening it to the plate. Fig. & is a modification of Fig. 1 and showsa plate without flanges and with only one calk fixed thereto. Fig. 5shows two plates fixed to the ends of a metal band to detachably connectthe ends of a flexible band as required in detachably fixing the band ona wheel. Fig. 6 is a modification of Fig. 1 in which a single calkextends from one end portion of the plate to the other. Fig. 7 is atransverse sectional view of Fig. 6 and shows it fixed to a section of aflexible band. Fig. 8 shows one of the plates having a calk connectedwith band-sections by means of hinge-joints. Fig. 9 shows my flexiblemetal band applied to a wheel as required for practical use. Fig. 10shows a section of the flexible band and a plate fixed on its endadapted for receiving a bolt as required for detachably and adjust-ablycon- (No model.)

meeting the ends of the flexible band. Fig. 11 is a top view of a bandcomposed of plates having calks and band-sections hinged together. Fig.12 is a top view of sections of a band hinged together and provided withintegral extensions and calks in alinement with said extensions. Fig. 13is a transverse sectional view on the line :r rr of Fig. 12.

The numeral 10 designates a flat-bottomed metal plate, preferably steel,that may vary in size as desired and as required to be fixed toflat-surfaced metal bands of different width. It has integral flanges 12at its ends adapted to slide over the edges of a fixed tire on atraction-wheel. It also has lateral extensions 13 at its sides, that areprovided with perforations to admit rivets for fixing the plate on ametal band. It also has enlargements 14 on its top provided with holesfor the admission of calks 15, as shown in Figs. 2 and 3. It is obviousfor a narrow band only one calk is required, as shown in Fig. i, andthat the flanges at the ends of the plate may be dispensed with.

A metal band 16 can be detachably and adjustably connected at its endsby means of a plate 17, fixed on the ends, and a screw-bolt 18 and nuts19, as shown in Fig. 5. The plates provided with calks may be fixed ontop of a metal band 16, as shown in Figs. 7 and 10, or they may behinged to sections 20 ot' a band, as shown in Figs. 8, 11, and 12, toproduce a complete flexible band by means of knuckles 21 integral withthe plates and knuckles 22 integral with the band-sections 20, or theplates 10 may have integral extensions 23, as shown in Fig. 12, to serveas band-sections for making a complete flexible band adapted to be fixedon a wheel by means of plates 17 at its ends and a screw-bolt and nutsin the same manner as shown in Fig. 5.

Having thus set forth the purpose of my invention and the manner of itsconstruction and application, its practical operation and utility willbe readily understood by persons familiar with the art to which itpertains; and

'hat I claim as new, and desire to secure by Letters Patent, is-

1. In a flexible band for traction-wheels, a

flat-bottomed metal plate adapted to be fixed on a band and providedwith a detachable calk extending outward, as shown and described for thepurposes stated.

2. A flat-bottomed plate, adapted to be fixed to a flexible metal band,provided with flanges at its ends and a detachable calk projectingoutward, for the purposes stated. I

3. A plate, adapted to be fixed to a flat flexible metal band, providedwith lateral perforated extensions and a detachable calk projectingoutward,as and for the purposes stated.

4. A flat-bottomed plate, adapted to be fixed to aflat-surfaced metalband, provided with an enlargement on its top and an aperture throughthe enlargement and a calk fixed in the aperture, for the purposesstated.

5. A flexible metal band, comprising a plurality of flat-bottomed metalplates connected with the band at spaces along the length of the bandand provided with detachable outwardly-extending calks and means fordetachably connecting the ends of the band.

6. A flexible metal band composed of sections' having detachable calksprojecting outward therefrom and metal plates fixed to the ends of theband and provided with upward perforated extensions to admit ascrew-bolt and nuts on the ends of the bolts, for the purposes stated. g

7. A friction-band for a tractionwheel comprising a flexible metal band,a plurality of metal plates connected with the band at distances apartalong the length of the band, detachable calks projecting outward fromthe plates, metal plates fixed to the ends of the band and provided withbolt-holes, a bolt extended through said bolt-holes and nuts on the endsof the bolts, for the purposes stated.

8. A friction-band for a traction-wheel comprising a flexible metalband, a plurality of metal plates connected with the band at distancesapart along the length of the band, detachable calks projecting outwardfrom the plates, metal plates fixed to the ends of the band and providedwith bolt-holes, a bolt extended through said bolt-holes and nuts on theends of the bolt, in combination with a traction-wheel, to operate inthe manner set forth, for the purposes stated.
